ALARMS AND ERRORS 

9.1

 

Alarms and errors 

The system supports a series of alarms related to both the system (memory, probes, communication, configuration, 
etc.), and the regulation algorithm (LoSH, HiSH, LOP, MOP, LowPressure). 
All the alarms, except the parameters alarm (EPar), are automatic, this means that they will be cancelled 
automatically once the cause of the alarm is removed. 
The presence of an alarm status is signalled using the LED interface and using relays, if suitably configured. 
The alarm status is always available in the Alarm status (AlSt), Configuration warning (CoWA) and Algorithm status 
(AlgS).

Memory error 

A memory error occurs when it is not possible to access data stored in the EEPROM memory: it is not therefore 
possible to access the parameter values stored on it, so they will assume default values from flash memory. Is also not 
possible to store new parameter values. 
This alarm can be occurred if the automatic conversion procedure of the temperature and/or pressure parameters is 
halted. In this case also the parameters alarm is set and is necessary to reload the default parameters from the flash 
memory to clear the memory alarm. 
 

9.3

 

Configuration error 

In the Stand-by off state the device configuration is checked for correctness of the parameters settings. If the 
configuration is not correct, an alarm is generated, signalled by bit 1 of Alarm status (AlSt). To determine the 
significance of this single bit Configuration warning (CoWA) contains the error code generated during the parameter 
verification process.
